First go at comet imaging ! 23 x 1mins at f/4.5 and focal length 360mm with an Atik314L+ (VMag 19 skies suburban Brisbane), stacked with DSS. Scope was an ED80 with a 0.6x reducer.

Not entirely sure what to do with processing comets, but fumbled along in Photoshop. Tail was much better than 5 days ago from Brisbane, I can now see about 10 streamers. FOV is about 1.6 degrees on diagonal.

Also ran through some photometry on the comet showing tail from 21.5 to 23 VMag/arcsec^2. I start to lose the tail from my skies at about 23.1, which equates to a SNR of about 2.5. Total integrated magnitude comes out at VMag 4.3+-0.2.
